Veratron Link Up Instruction Manual page 11

CONNECT TO THE NMEA 2000® NETWORK
Once the sensor installation is complete it is possible to interface
the Link Up gateway to the NMEA 2000® network through the
dedicated DeviceNet plug.
Please ensure to tighten the M12 connector by screwing it onto its
counterpart, so to preserve the water tightness.
A drop cable is not needed unless the total length of the Link Up
device is not enough to reach the NMEA 2000® backbone. In this
case it is possible to extend the total length by using one of the
accessory drop cables.
Please note that NMEA 2000® does not allow drop cables longer
than 6 meters.
Refer to the NMEA 2000® standard for a proper network design.
If power from the NMEA 2000® network is received, the green
LED on the Link Up housing will start flashing (see "LED
notifications").
